fix sysvfs symlinks

2016-10-26T15:15:33Z

commit 0ebf7f10d67a70e120f365018f1c5fce9ddc567d upstream. The thing got broken back in 2002 - sysvfs does *not* have inline symlinks; even short ones have bodies stored in the first block of file. sysv_symlink() handles that correctly; unfortunately, attempting to look an existing symlink up will end up confusing them for inline symlinks, and interpret the block number containing the body as the body itself. Nobody has noticed until now, which says something about the level of testing sysvfs gets ;-/ Signed-off-by: Al Viro [lizf: Backported to 3.4: adjust context] Signed-off-by: Zefan Li

vfs: check i_nlink limits in vfs_{mkdir,rename_dir,link}

2012-03-21T01:29:32Z

New field of struct super_block - ->s_max_links. Maximal allowed value of ->i_nlink or 0; in the latter case all checks still need to be done in ->link/->mkdir/->rename instances. Note that this limit applies both to directoris and to non-directories. Signed-off-by: Al Viro

switch ->create() to umode_t

2012-01-04T03:54:53Z

vfs_create() ignores everything outside of 16bit subset of its mode argument; switching it to umode_t is obviously equivalent and it's the only caller of the method Signed-off-by: Al Viro

switch vfs_mkdir() and ->mkdir() to umode_t

2012-01-04T03:54:53Z

vfs_mkdir() gets int, but immediately drops everything that might not fit into umode_t and that's the only caller of ->mkdir()... Signed-off-by: Al Viro

vfs: fix the stupidity with i_dentry in inode destructors

2012-01-04T03:52:40Z

Seeing that just about every destructor got that INIT_LIST_HEAD() copied into it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once(); the cost of taking it into inode_init_always() will be negligible for pipes and sockets and negative for everything else. Not to mention the removal of boilerplate code from ->destroy_inode() instances... Signed-off-by: Al Viro
